Title: Hall-effect memory device
IPC: G11C27/02
Filed: 1964-01-27
Abstract: 1,044,553. Hall plates. F. R. BRADLEY. Jan. 27, 1964, No. 3407/64. Heading H1K. [Also in Division H3] A signal amplitude memory device comprises a Hall plate located in a hard iron magnetic circuit to which the signal and the Hall output are applied in opposition. In Fig. 1 (not shown) the field winding 18 is connected to the signal source V S  and in reverse sense to the Hall output electrodes 24, 26. As the magnetization increases the Hall output voltage increases until the Hall storage equals the signal voltage whereupon the current flow ceases. Read out is effected by measuring the Hall voltage. A highfrequency oscillation may be applied to a coil 28 to render the circuit sensitive to small signals, the oscillation being provided from an external source or by the resonant discharge of a capacitor 34. If the Hall current is increased after the storage has been effected the Hall voltage will correspondingly increase and a large output voltage is biased. The D.C. current in the current electrodes may be replaced after storage has been effected by an A.C. current so that an A.C. output is produced. When the input signal is A.C. it must be rectified before applying it to the coils (Fig. 4, not shown). In Fig. 3 (not shown) the input signal at 20 and the Hall voltage at 21 are applied in opposite sense to the coils through an operational D.C. amplifier. During read-out the switch 36 is moved to connection 1 so that the same amplifier is used for the output signal. Opposite polarity signals are thus available at terminals 41 and 20. If the Hall current plates are supplied from an A.C. source the signal also may be A.C. in which case the combined A.C. signal and Hall voltages must be rectified before application to the field coil (Fig. 5, not shown).

Abstract: 542,990. Carbon disulphide. CARBONISATION ET CHARBONS ACTIFS. Feb. 23, 1940, No. 3427. Convention date. Feb. 24, 1939. [Class 1 (ii)] [Also in Group IV] During processes of rayon manufacture, carbondisulphide, which may be tainted with products such as sulphurous anhydride or sulphuretted hydrogen, is extracted from the coagulation, washing and finishing baths, or from the bobbins of coagulated threads, by drawing a current of air above the baths and bobbins and conducting to wet and dry activated carbon. The thread 1 from the pot 2 enters the xanthate coagulation vessel A and passes through a narrow outlet to the reel B surmounted by a hood 7. Wound reels B', B<SP>2</SP> are supported in the washing and drying vessel C ; a pipe 9 connects the vessels A, C and the hood 7 to the inlet of the fan D which induces a current of air through the apertured lid 3 of the vessel A so that the carbon disulphide is carried on to the fan and passed to the absorber E. The first part of this contains activated carbon highly charged with water to absorb the sulphur compounds, and the second part contains practically dry activated carbon to absorb the carbon disulphide. The flow of gas may be controlled by valves placed at each stage.
